What about the large-scale human sacrifice in Shang Dynasty? Why is it not recorded in historical materials? Since the ancient slave society (or earlier), human beings have had the custom of martyrdom. There has never been an anti-slavery social revolution in the history of China, but with the improvement of people's civilization concept, there are fewer slaves, and some emperors and nobles gradually replaced large-scale slaves with terracotta warriors and horses, the most typical of which is the Terracotta Warriors and Horses of Qin Shihuang. However, in China's aristocratic and bureaucratic families, slavery has always existed, but it is no longer called slaves, but called domestic slaves and domestic slaves. However, the householder has no power over domestic slaves, otherwise the government will investigate them. In the royal family, the emperor was buried until the early Ming Dynasty. According to records, when Zhu Yuanzhang, the founding emperor of the Ming Dynasty, died, many concubines were buried. Until the middle of the Ming Dynasty, there was an emperor (I can't remember the name) who loved his wife deeply and refused to take a concubine. When he was old, he thought that when he died and was buried, his queen was buried, which was unacceptable! So he ordered that, starting from him, people should not be encouraged to die. China's martyrdom ends here.

Why are there no written records about the archaeological discoveries of large-scale martyrdom in Yin and Shang Dynasties? I think it should be that China's writing (Oracle Bone Inscriptions) was still in the primary stage in Shang Dynasty, and it was not used to describe history in detail, but only used for divination. Therefore, the history of Yin Shang belongs to oral history, and it is inevitable that there will be mistakes and omissions in the history recorded by people after the Zhou Dynasty according to oral words. Therefore, the country started the Xia, Shang and Zhou Dynasties Dating Project, and through archaeological excavations, the possible mistakes and omissions in the history recorded in words after oral circulation were verified and corrected.

There were almost no formal characters in Shang Dynasty, and there were no record carriers such as bamboo slips and Du Mu. Most of the notes are engraved on tortoise shells or animal bones, mostly for divination. At that time, martyrdom was common, because there was a concept of death. If a family or even a country is rich, it must take its enjoyment or love underground after death. For fear of future generations, the parties concerned will not disclose the details of the burial, for fear of disclosure, and even kill the insider and bury him in the mausoleum. Detailed records are handed down from generation to generation by sorting out some rumors or rare records of later generations, or records obtained after tomb excavation. For example, the priceless cultural relic of the Han Dynasty unearthed in Nanchang, Liu Biguang of Hanwang, Jinan, was not widely used at this time, but spiritual civilization had been established.
